Passive Voice All Tenses

Respuesta correcta: B) are cleaned

• A) cleanNo. 'clean' is the active verb of the janitor, so the sentence says the janitor does it. The passive needs 'are cleaned', because the action is emphasised, not the doer.
• B) are cleanedCorrect! Present simple passive is 'are' plus the past participle, and the subject 'the classrooms' is plural, so 'are cleaned' is the only form that fits.
• C) is cleanedNo. 'is cleaned' is singular and the subject here is 'the classrooms'. Choosing it would break the agreement in number between subject and auxiliary.
• D) have cleanedNo. 'have cleaned' is active and perfect, and it would make the classrooms the doer. Nothing in the sentence is doing the cleaning; the action matters, not the agent.

Respuesta correcta: C) is being built

• A) is builtNo. 'is built' is present simple passive. The adverb 'right now' asks for an action in progress, which needs the continuous form.
• B) was builtNo. 'was built' places the construction in the past, but nothing in the sentence refers to a finished past action.
• C) is being builtCorrect! Present continuous passive is 'is being' plus the past participle, and it describes a construction that is happening at this moment.
• D) has been builtNo. 'has been built' presents the construction as a finished result relevant now. Here the emphasis is on the process still going on, not on the completed building.

Respuesta correcta: A) was opened

• A) was openedCorrect! Past simple passive is 'was' plus the past participle 'opened', which is exactly what a finished event in 1998 requires.
• B) was openingNo. 'was opening' is a past continuous form and would describe an unfinished action, but the opening of the bridge was a single completed event.
• C) were openedNo. 'were' is plural and the subject 'the bridge' is singular. The verb 'open' does not change the number agreement in this passive.
• D) had openedNo. 'had opened' is active past perfect: the bridge would be doing the opening. The action here is received, not performed.

Respuesta correcta: D) were being inspected

• A) were inspectedNo. 'were inspected' is past simple passive and presents the inspection as finished. The clause 'when the alarm sounded' shows it was still running.
• B) are inspectedNo. 'are inspected' is present simple passive and would place the inspection now, but the whole story takes place in the past.
• C) have been inspectedNo. 'have been inspected' is present perfect passive and links the inspection to the present, which is not the time frame of the sentence.
• D) were being inspectedCorrect! Past continuous passive is 'were being' plus the past participle, and it matches an inspection that was in progress when the alarm interrupted it.

Respuesta correcta: C) has been visited

• A) has visitedNo. 'has visited' makes the historic centre the visitor. The subject receives the action, so it needs a passive form with 'has been'.
• B) had visitedNo. 'had visited' is active past perfect and again gives the subject the role of the doer, which contradicts the meaning.
• C) has been visitedCorrect! Present perfect passive is 'has been' plus the past participle, which links a past action to a present result without giving a date.
• D) was visitingNo. 'was visiting' is an active past continuous and would require the historic centre to be doing the visiting, which is impossible.

Respuesta correcta: B) will be announced

• A) announceNo. 'announce' is an active base form with no auxiliary. A passive sentence must show the tense with 'will be' plus a past participle.
• B) will be announcedCorrect! Future simple passive is 'will be' plus the past participle, and 'tomorrow morning' fixes the publication in the future.
• C) are announcedNo. 'are announced' is present simple passive and would mean the results come out every morning, which contradicts 'tomorrow'.
• D) will announceNo. 'will announce' is the future active and would make the exam results the ones doing the announcing.

Respuesta correcta: D) is going to be repaired

• A) will repairNo. 'will repair' is the future active and makes the highway the doer of the repair, which is not what the sentence states.
• B) is repairingNo. 'is repairing' is present continuous active and would claim that the repair is happening now.
• C) repairedNo. 'repaired' has no auxiliary at all, so it carries neither tense nor voice. English requires a form of 'be' in every passive.
• D) is going to be repairedCorrect! The passive of 'going to' is 'is going to be' plus the past participle, and it expresses a plan already decided for a future date.

Respuesta correcta: A) can be read

• A) can be readCorrect! Modal 'can' plus 'be' plus the past participle forms the modal passive, and it expresses what everybody is able to do with the handbook.
• B) can readNo. 'can read' is the modal active and would make the handbook the reader. The real subject of 'can' here is the student, not the book.
• C) is readNo. 'is read' is present simple passive and states a habit, without any reference to what students are capable of doing.
• D) was readNo. 'was read' is past simple passive and would claim the reading happened in the past, which the sentence never mentions.

Respuesta correcta: C) had been closed

• A) had closedNo. 'had closed' is the active past perfect and would make the road the element that closes itself, which is not something a road can do.
• B) would closeNo. 'would close' is the modal active form of the condition and keeps the agent, so it does not belong in a passive conditional.
• C) had been closedCorrect! Third conditional passive is 'had been' plus the past participle, and it describes an unreal past condition that would have changed the outcome.
• D) has been closingNo. 'has been closing' is present perfect continuous, which is active and refers to an action that started in the past and is still going on.

Respuesta correcta: B) must be respected

• A) must respectedNo. 'must respected' skips the form of 'be' entirely, which is ungrammatical in the passive. English needs 'must be respected'.
• B) must be respectedCorrect! 'must be' plus the past participle is the modal passive of obligation, and 'at all times' reinforces that the rule has no exception.
• C) are respectedNo. 'are respected' is present simple passive and expresses a custom, not the strong obligation that 'at all times' signals here.
• D) must respectNo. 'must respect' is the modal active, which would make the rules the ones doing the respecting instead of the ones being respected.

Respuesta correcta: D) was given

• A) givesNo. 'gives' is the simple present active, but the recognition arrives at the ceremony; it is not something the mayor hands out while speaking.
• B) has givenNo. 'has given' makes the mayor the giver of the recognition and marks the action as completed, which reverses the meaning.
• C) is givingNo. 'is giving' is present continuous active and again puts the mayor in the role of the person performing the action.
• D) was givenCorrect! Past simple passive 'was given' puts the mayor in the role of the receiver, which is the whole point of choosing the passive in this sentence.

Respuesta correcta: A) to be done

• A) to be doneCorrect! The passive infinitive 'to be done' is required after 'there is nothing', because the wall is the thing affected and not the one acting.
• B) to doNo. 'to do' is the active infinitive and would make the wall the element that does something, which contradicts 'nothing'.
• C) doingNo. 'doing' is a gerund form and cannot complete the structure 'there is nothing' without a form of 'be' before the participle.
• D) doneNo. 'done' alone has no infinitive marker and no auxiliary, so the phrase 'there is nothing done' is not a grammatical passive construction.

Respuesta correcta: C) were broken

• A) brokeNo. 'broke' is the active past simple and makes the windows the agents of the action. Windows cannot break windows.
• B) are breakingNo. 'are breaking' is present continuous active and describes a continuing action, which contradicts 'during the night'.
• C) were brokenCorrect! Past simple passive 'were broken' matches the plural subject 'the windows' and the past time expression 'during the night'.
• D) have brokeNo. 'have broke' is grammatically wrong because the past participle of break is 'broken', not 'broke'.

Respuesta correcta: B) were

• A) didNo. 'did' is the auxiliary of the active; it needs a subject and a verb after it, and it cannot open a passive question on its own.
• B) wereCorrect! A passive question is formed with the subject first, then the auxiliary 'were' plus the past participle, which yields the interrogative word order 'were the documents transferred'.
• C) wasNo. 'was' is singular and the subject 'the documents' is plural. The number agreement must be respected even in an inverted question.
• D) haveNo. 'have' works with participle forms in perfect tenses but does not invert into a passive question about a definite past date such as this one.

Respuesta correcta: D) cannot be made

• A) will not be madeNo. That form is possible in isolation, but the context describes a consequence of an unfinished approval in the present, which the present perfect passive negative expresses more directly.
• B) was not madeNo. 'was not made' places the failure in a closed past, while the sentence is about a situation that is still unresolved now.
• C) is not being madeNo. 'is not being made' describes an action currently in progress, but nothing indicates that a payment is under way right now.
• D) cannot be madeCorrect! 'cannot be made' expresses the impossibility created by the missing approval, and the modal passive fits the causal link between the two clauses.

Respuesta correcta: A) The goods were moved to the second warehouse.

• A) The goods were moved to the second warehouse.Correct! This is the past simple passive: the goods are the subject, they receive the action, and no worker is named, which is exactly what the instruction required.
• B) The goods were moving to the second warehouse.No. This is a past continuous passive, which would describe a movement still in progress. The report refers to a completed transfer between two warehouses.
• C) The goods moved to the second warehouse.No. This is the active past simple and it makes the goods the agents of their own transfer, which is semantically impossible.
• D) The goods have moved to the second warehouse.No. This is the active present perfect, so the goods perform the action, and it also links the move to the present in a way the report does not require.

Respuesta correcta: B) to be signed

• A) signingNo. 'signing' is a gerund and belongs to a different construction. 'Needs' followed by a gerund describes a habitual action, not a single requirement.
• B) to be signedCorrect! 'needs to be signed' uses the passive infinitive because the application is the document that must receive the signature.
• C) signNo. 'needs sign' is not grammatical after the modal-like verb 'need'; a form of 'be' plus participle is required in the passive.
• D) being signedNo. 'needs being signed' mixes a gerund with a passive participle. English does not allow 'need' plus 'being' plus past participle here.

Respuesta correcta: A) was cleaned

• A) was cleanedCorrect! The garden receives the action, so the past simple passive is right, and the agent appears only in the 'by' phrase as an optional detail.
• B) cleanedNo. 'cleaned' with no auxiliary has no tense and no voice. A bare past form cannot stand alone as the verb of a complete clause.
• C) is cleanedNo. 'is cleaned' is present simple and would describe a habit that still continues, but the phrase 'for years' points to a period in the past.
• D) has cleanedNo. 'has cleaned' is the active present perfect and would make the garden the person who cleans, which is exactly what a passive avoids.

Respuesta correcta: C) has not been damaged

• A) has been damagedNo. 'has been damaged' is grammatically correct, but the adverb 'yet' in a negative clause expects 'has not been damaged', so the sentence as written changes the meaning.
• B) was damagedNo. 'was damaged' presents the damage as a closed past event and cannot be combined with the negative adverb 'yet' in the way the sentence does.
• C) has not been damagedCorrect! The present perfect passive negative is 'has not been' plus the past participle, and 'yet' at the end fits that structure perfectly.
• D) is not damagingNo. 'is not damaging' is active and would make the equipment the cause of the damage, which is the opposite of what the report says.

Respuesta correcta: D) was rebuilt

• A) rebuiltNo. 'rebuilt' alone carries no auxiliary, so it can never form a complete clause in English. A passive needs an explicit form of 'be'.
• B) has rebuiltNo. 'has rebuilt' is the active present perfect and makes the roof the agent of its own reconstruction, which is not the intended meaning.
• C) is buildingNo. 'is building' is present continuous active and would mean the roof is performing the action at this moment.
• D) was rebuiltCorrect! 'was rebuilt' is the past simple passive, and the instrument phrase 'with contributions' explains how the rebuilding happened without naming a single agent.
